ABSTRACT:
A ditch, for example in the form of a cable or pipe channel, is uniformly filled with sand with the aid of a movable, funnel shaped container (1) for the sand, equipped with a conveyor feed screw (6) reaching from the container bottom to a container discharge member at an upper edge of the container. The discharge member includes a discharge opening in the upper container edge (5) below the upper end of the feed screw (6). A second conveyor in the form of a chute (7) is arranged to reach with its upper end to a point below the discharge opening when the chute is provided into its operating condition. The lower end of the chute reaches over the central area of a ditch (11). A guide member (8) at the lower end of the chute reaches into the ditch and slides or rolls along one ditch wall. Thus, the lower end of the chute which is able to swing or journal about a vertical axis, is maintained above the ditch even if the container on a carriage does not move exactly in parallel to the ditch.
